The Inevitability of Radical
Climate Change: A Short Assessment
Among
those who are professionally qualified to make such judgments, there is virtual
unanimity that human activity causes the earth’s climate to increase to the
point when it will make far larger and more devastating changes than warming
has so far. Dissenters from these predictions don’t put forward evidence
refuting those claims, but simply assert “I’m not a scientist,” as if that
dubious status entitles them to disagree with those who have actually studied
the mechanisms of climate change.
If things are left to go as they now are, the second half of the 21st
century will see extended droughts, vast increases in deaths caused by heat,
devastating flooding in coastal areas that will not be respecters of important
cities, and much more, including undesirable effects on virtually all living
things on land and sea. I feel sorry for my grandchildren’s grandchildren who
will be living during the period when things get really bad. But surely, you say, these
horrible effects can be forestalled. Just as it is known what horrors will be
brought on by climate warming, it is known what needs to be done to sharply
reduce if not eliminate it altogether. Moreover, that warming is not brought on
by natural processes over which humans have no control, but by human activities
that take place everywhere on the globe—to be sure to sharply varying degrees.
Stop them or at least decrease them notably and those disasters won’t happen.
But
there is a fateful wrinkle. What needs to be done is costly and where they are
enacted virtually everyone is affected either by increased living costs or
decreased income or both. This dual effect of countermeasures makes me totally
pessimistic that very much will be done until the worst effects of warming have
begun to make their appearance and when its effects, moreover, have become
irreversible.
What is the
basis of this gloomy prediction? To a greater or lesser degree—and nowhere to
so small a degree that it can be ignored—those who rule are dependent on the
good will of the populations over which they preside. How that is so in
democracies—in Western Europe and the United States—is obvious. But it is
equally true, just different, in China and Russia. Putin and Xi Jinping may certainly
have considerably greater latitude than Obama in the treatment of the
populations they govern, but they too must pay heed to the warning Machiavelli
issues in The Prince: people will
forgive you for killing their fathers, but they will not forgive you for taking
their patrimony.
To take
effective measures against global warming is to making present sacrifices for a
future goal, indeed a goal that lies considerably beyond the lifetimes of those
who would be paying now. People, some anyway, may be willing to give up
something for the benefit of their grandchildren, but the more remote they are
from such family beneficiaries, the less inclined they will be to make
sacrifices.
Take
just a single real life example. Mitch McConnell, a senator from Kentucky for thirty years and now
majority leader, surely smart, professes to hold that there is no global
warming and if there is, human activities are not a cause. Of course I don’t
know what he actually believes; but
what I do know is that he is the senior senator of a coal-mining state and
measures to reduce future global warming would, with certainty, have a negative
effect on the economy of the senator’s state and its citizens.
I’m
pessimistic because today just about
always trumps tomorrow and acting to
save oneself surely trumps saving others—not to mention unknown others. In
short, significant (and costly) measures will be taken when significant damage
has already been done. I won’t be around when that happens.
